At Trezor, security is the foundation of everything we build. As the inventor of the first hardware wallet, we have helped shape security standards widely used across the crypto space, including Recovery seeds, Passphrases, and Shamir Backup. Founded in 2013 and still 100% self-owned, we continue to build open-source products that give people more control over their digital assets.
As a Cryptographer Team Lead, you’ll bring strong cryptographic expertise into real product development and help guide this domain across Trezor. In this role, you’ll work on practical cryptographic challenges, contribute to security-related decisions, and lead a small team of specialists. This is a great opportunity for someone who enjoys turning complex concepts into practical solutions and wants to have a visible impact on products used by millions. If that sounds like your kind of challenge, read on.
